The cloud PDF trap

Smallpdf charges $15/month. iLovePDF locks 2-of-3 core tools behind signup walls. Adobe Acrobat starts at $18/year just to merge two files.

PDF Tool does everything for free. Right now. In your browser.

Privacy that actually means something

When you upload a contract to Smallpdf, their server touches it. When you use Adobe online, Adobe's cloud processes it. Even if they don't store it, it traversed someone else's wire.

PDF Tool uses pdf-lib — the entire PDF engine runs as JavaScript on your machine. Zero network requests for file data. After the page loads, you can even go offline and keep working.

This matters when your PDFs contain:

HR documents with salary bands
Legal agreements with NDAs
Financial statements
Anything you wouldn't want a third-party server to see, even briefly

Build vs buy math

Let's be real about the $19 one-time option. If you're a freelancer, consultant, or small team who touches PDFs more than three times a month:

Smallpdf annual cost: $15 × 12 = $180/year
PDF Tool Pro (one-time): $19

That's a $161 savings every year, forever. And the free tier already covers 95% of use cases indefinitely.

New: Side-by-side comparison pages

We recently built dedicated /vs/ pages so you can see exactly what you're trading off before you commit:

Each breaks down features, pricing, and privacy trade-offs so you can make an informed call.

How it works

The tool ships as a single-page app. Load https://pdf.jackgreen.top, pick your operation (merge, split, or optimize), drop your files in — that's it. No buttons to click, no accounts to create, no captchas to solve.

Everything happens in-memory via pdf-lib. There is no backend to scale, no database to manage, no secrets to rotate. This is the kind of architecture that stays fast because it has nothing to talk to.
